Segmentation fault with simple code and Python 3.11

[vincbo]

The following code

import ormsgpack

ormsgpack.packb("hello")

leads to a segmentation fault on the following configurations:

ormsgpack 1.4.1 + Python 3.11.7 on Debian 12
ormsgpack 1.4.1 + Python 3.11.6 on macOS sonoma 14.2.1

To reproduce, copy the content in file called test.py for example and execute the command:

python3 test.py

The example works fine with Python 3.9.16 and Python 3.10.10.
